[f. onco- + -otic.]
Applied to the osmotic pressure exerted by a colloid, esp. plasma protein.
1935C. J. Wiggers Physiol. li. 802 Starling demonstrated that colloids in a sol state exert a small osmotic pressure, but this varies in uncontrollable fashion owing to the fact that colloidal molecules or aggregates called micellae vary considerably. This has tersely been called oncotic pressure. 1977Proc. R. Soc. Med. LXX. 693/1 A reduction in oncotic pressure due to hypoproteinaemia. |
